You start in Jungle, and a patch of Bamboo Jungle sits only about 128 blocks from spawn, which is a rare find this close. River, Sparse Jungle and Dark Forest all begin within about 64 blocks, so the early game has varied wood and terrain. An Ancient City lies about 286 blocks west of spawn at (-288, 80), reachable on foot. The Ocean Monument is a longer trip, about 988 blocks south-east.
